F0 (S.I.F.T, for speech) method

From STX Wiki

Computes the fundamental frequency track of speech signals using a modified SIFT algorithm (= Simplified Inverse Filter Tracking). This method measures the period duration of the downsampled and pre-whitened signal and is optimized for speech signals. The result is the parameter function F0A(t) which can be saved in the project.
